Question 1

How much does it cost to replace an HVAC system in Canada?

Accepted Answer

HomeStars' 2026 guide puts a combined central furnace-and-AC system around $8,500–$20,000+ installed, so a mid-size home replacing both at high efficiency with the existing ducts reused lands near $14,250 before tax. A single unit, a ductless mini-split, or a standard-efficiency tier costs less. Use the calculator above for a range matched to your home size, system type, and efficiency. Prices shown are before GST/PST/HST, which is added per-province at billing.

Question 2

Should I replace the furnace and AC at the same time?

Accepted Answer

If both units are near the end of their life, replacing them together is usually cheaper than two separate jobs — the crew shares one trip, one set of permits, and matched components run more efficiently. Choose 'Full system (furnace + AC)' to price both; pick a single component if only one unit has failed.

Question 3

Which efficiency tier should I choose?

Accepted Answer

Standard efficiency is the budget choice; high-efficiency (higher SEER2/AFUE/HSPF2) is the durable mid-grade that lowers running costs in Canada's long heating season; premium variable-speed equipment sits at the top for comfort and the deepest energy savings. Pick the tier that matches your climate and budget — the calculator scales the estimate accordingly.
